[origin: EP0811438A2] The press has the material (39) passed through the machine between two pairs of grip and transport rollers The sheet is clamped during perforation by an array of stamps. The output of the press passes through a set of special stamps (36) which produce selected patterns of holes or slots at the edges of the perforated sheets. The selected holes are produced by selecting stamp patterns in the stamp holder and by moving the stamps laterally into the selected positions.
